VIBRATING PROPELLER FOR BOATS.

SPECIFICATION forming part of Lettera Patent No. 278,945, dated June 5, 1883.

Applieation tiled August l5. 18H2.

To alt whom, it may concern.-

Be it known that I, HENRY A. HANS-UM, ot

Cazenoriu, in the eount51 ot Madison and State New York, have invented new and useful -nprovements in Boats for Hunting Wild nvls, of which the following, teken in coneetion with the accompanying drawings, is n di. clear, and. exile-tdescription.

This invention consists in n. novel eonstrne- :ion ot'n boat-propeiling apparatus designed to be noiseless and capable of operating in shal low as well as deep water, and thus specially adapted for hunting wild fowl und other garnie on or near the water.

The invention also eonssts in certain novel mea-ns for operating the aforesaid propeller, all as hereinafter more fully explained. nud set forth in the. elninis.

Referring to the annexed drawings, Figure. 1 is a longitudinal section of nbont,illust1ating the manner of propelling the bout. Fig. 2 is nu exterior side View ofthe sume. Figs. Sund t nre plan views ofthe bont, respeetively with and without n eover. Fig. :"1 is u transverse section on line rw. Fig. 6 is n trnnsvelse seetion ofthe upper portion ot' the honi und its appurtenances, taken on line y y. Fig. is n n view ofthe supplemental cover for elusthe openings or ports of the lnnin rover. L ig. 8 is an enlarged isolnet'rie view ofthe paddle detached. Fig. 5l is n further enlarged horizontal tlnnsverse section of the puddle proper. Fig. 10 is n detail view of thejoint of the paddle-rod, und Fig. 11 illustrates the opera-tion of the paddle in shallow water.

Upon the gunwzl-les of this liront-,11nd dinmetrieolly opposite eheh other, ure-iirnilv secured two boxes or jourmdJJea-rings, l l. preferably formed ol' wood. in veel: of said hen-ritme is hung a pzuldie composed of ashort horizontal sha-ii, x. journnled in the hearings l, and susto-ined luternlly by eollurs ron Suid sha it', abutting uga-inst opposite ends ot' the lmuringnn crunk, L', pendent from the inner end o' the shnii e. nud the puddle proper, pendent from und rigidly nttnehed to the outer end ol snid sllnt't' :nid in proximity to the side ofthe bord.

PATENT OFFICE.

(No mmlnin u', having n sharpened lront edge, so as to easily more through the water.

To the rear edge ofthe rod a is rig-idly nltnehed a rectangular skeleton t'rnlne, d, and nl opposite sides ofthe t'rnme are two wings, e ff. hinged on the rod a', snid wings being' formed of two thieknesses of leather. rubber, or analogous sheet material of proper width to la'p onto the sides of the frame d. These wings are stiened by u metal plate, y, inserted hetween the aforesaid two sheets or blades. The action of the wings is limited hiv strnpsf j', preferably ot' len-ther, connected :1t one end to the f1n1ned,nnd ut the opposite end to the outer or free edge ot` the wings, as host seen in Fig. 9 of the drawings. The objet-t of employ: ing leather :is the materiel for the wings and their straps is todenden the eoneussion ofthe wings against the finme d :1nd to render the :1c-tion ofthe paddle noise-less.

in order to adopt the paddle for operation in 'shallow ns well as deep wntexgl eonstrnet the matin or supporting' rod of the paddle of two-sections, u o', joined with overlapping ends n. which are bowed ont wurd from rneh other intermedintelj.' of the length ot' the overlapping portion, as lshown in Fig'. lo ofthe drawings. the end of one bnr, u". being; hinged on the side ot the other bnr. u, und provided in the center ofthe :llores-.lid overlapping parlwith n stud or elnspdiuttou, b. The rear edge ofthe burn is provided with n noteli, e. adopted to receive the shank ofthe button I. This shank is so eurtniied in length that when the bnr u' is swung into line with the bnr a the under side ot' the hond ofthe button b will encounter the outer thee ofthe bnr u, nud draw the bowed overlapping: ends n"l together. und thereby hind or elnlnpthejointed hors to snel: un extent :is to ennlile the puddle to poss through the water during; the :ilin'esoid morenient ofthe puddle without trippingr or loosening the aforesaid joint.

The deseribed peenlinr etnistrlu-tion ol the clump nl'theiointed puddle-hors, while eupuhle ol' resisting: the pressure of the wutennsuloresaid. is enpnhle of nutonult irull) tripping.;` itsel t' to allow the puddle proper to swing.r renrwnrd from the inn' n" in enses-uid puddle eneounters rigid obstruetions iu the waiter. or is enrried into shallow nier und reused to strike the hot-toni. us illnstinted in Fig'. ll ol the dmwings, in which latter ease the paddle operates in the manne-r of a pole.

To the lower end of' the. eranks I.- ot' eat-h paddle is connected a pitman, i, :md the. two pitmen are extended along the interior ot' the boat and connected to opposite ends ot' a snpplemental treadle, l, inthe forni of n horizonml cross-bar pi voted at its center to the bottom of the interior oi' the boat, as shown in Figs. -L oft-he d 'uwings The'deseribed paddles being operated by a person sitting orreelining; on the bot-toni ot' the bo'atfacing the boni, and pressing with his 'feetaga'xnst the rear oi' the crank-pin alternately atopposite sides of the boat, the i'orward motion ot' one frank imparts a rearward mot-ion to the opposite. cra-nl; by the medium ot' the ptinen 'i Ii, and pivoted supplemental trendlc h. The rearwardlymoving rrauk,car rying with it. the paddle connected therewith, causes the win gs e e ot' the latter to bceoine distended by the resista-nee ot' the wat-er, and this` resista-nee propels the boat.

It will he observed that. by the arrangement of the supplemento-l treadle and ptinen transmitting mot-ion from one side of the boat to the other the person propelling the boat enabled to i'aee the bow ofthe bont, which in this ease is ver)v essential. Furthermore, the supplemental treadle I: affords additional inea-ns i'or applying propelling-power, inasmuch as a second person can appl)- his feet thereto and operate it-in the smile manner as the first person operates the cranks, as illustrated in Fig'. l of the drawings.

Having' described my invention, what l ola-ini as new. and wish in secure by Letters Patent, is

1. The within-described combined poling and paddling propeller-.consisting of a paddle rod or stem provided interinediately ot' its length with a--forward deflect-ing joint and a, friction el'uteh connected :with said joint, whereby the paddle rod receives suicient st iness to resist the pressure of the water when operated as a paddle, and is enabled to nutonnatenlly trip itsjoint when encountering rigid obst rue-tions, and to operate in the manner ot' poling on the bott-oni of shallow water, substantially as described and shown.

2. The paddle-rods n a', overlapping each other, with bowed ends e?, hinged together -at theend of one of said rods, one of seid bowed parts being' provided with a clasp-button, b, and the other bowed part being adapted to slide. under the head of the bntt-omand having a noteh, e. for the reception of the shank ofthe button, the whole constructed, combined, and operating to automatically elamp the joint, of said rods, substantiallyr as shown, and for the purpose set forth.

3. In combina-tion with the rod a' und its frame. d, the wings e, formed respectively of leather blades and a stiffening-plate, g, between the leather blades, substantially as de scribed and shown.'

4. The combination, with thc paddle a n', fixed to shaft s, and provided with the crank k, of the pitnian i. and the horizontal lever la, pivoted at its eenter'to the bottom of the interior ot' the boat, substantially in the manner described and shown, for the purpose specified.

ln testimonv whereof I have hereunto signed my naine and aiixed my seal, in the presence of two attesting witnesses, :it Cazenovio, in the county of itadison, in the State ni Xew York, this 19th day of July, lSSi..
